Open Question: Looking for an old web based game.?

I used to play a web based game where you could buy a castle and soldiers and weapons and such, then you would search a list of other players to attack around your current level. Depending on your worth and defenses you would move up in rank amongst the other players. I saw my sister playing a mobster like game with the same kind of rules on myspace. There was also a dark elf like race that had the ability to poison other soldiers during a fight and get you a few more kills, and gold was taken from the person who's castle you attacked if you won.
